2.3 Dimensional drawings
In this chapter, you can find the dimensions of the gear units as well as example dimensions of the mountable motor adapters.
Dimensions can exceed the specifications of ISO 2768-mK due to casting tolerances or accumulation of individual tolerances.
We reserve the right to make dimensional changes due to ongoing technical development.
You can download 3D models of our standard drives at https://configurator.stoeber.de/en-US/.

In this chapter, you will find the description and technical data of the motor adapter with brake.
2.5.2.1 Properties
• Electrically actuated spring-loaded brake for dry running
• Featuring backlash-free plug-in coupling (jaw coupling) for easy removal of the motor with the axis
braked in any position
• Electrical release monitoring in the terminal box of the motor adapter
• Manual monitoring of wear via air gap checks with a feeler gauge
• As a single brake or together with the motor brake as a redundant brake system
• Manual release (optional)
• Radial shaft seal rings made of FKM with two sealing lips
• Four oil drain holes to protect the brake from oiling up in case of leakage
• Fast and easy motor attachment

2.5.2.2 Brake
A quiescent current brake is integrated into the motor adapter. It has the function of a holding brake. Braking from full speed, e.g. in case of a voltage drop or an emergency off in hazard situations, is still possible.
The brake can be used as a single brake or together with the motor brake as a redundant brake system.
Function
The brakes installed in the motor adapter are electrically actuated spring-loaded brakes for dry running. In
the de-energized state, braking takes place using spring force. The brake is released by an electromagnetic
DC coil before the motor is switched on. The switch-on time t2B (release time) is the time until the anchor
plate releases from the axially moving brake disc and is magnetically held to the coil body. In this state, the
brake is released and the coupling hub can rotate. In order to switch off (motor and brake), the residual
magnetic flux of the iron parts (anchor and coil body) must be reduced; the associated time t11B until the
start of torque generation is defined as a response delay when linking. The link time t1B is the time until the
braking torque has built up to the nominal braking torque.
Manual release
Optionally, the brake can be equipped with a manual release.
Pressing the manual release deactivates the electronic actuation of the brake. Before pressing the manual
release, you must establish the safety of the machine (e.g. protection against falling).
2.5.2.3 Electrical connection
• Terminal box (standard)
• Plug connector (optional, not possible in combination with release monitoring)

2.5.2.4 Monitoring
For monitoring the brake system, there are generally two options:
• Manual monitoring of wear via air gap checks with a feeler gauge
• Electrical release monitoring in the terminal box with a non-contact and wear-free proximity switch

2.6.4 Recommendation for radial shaft seal rings
For a duty cycle > 60% and higher surrounding temperatures, we recommend radial shaft seal rings made of
FKM at the output.
Properties:
• Excellent temperature resistance
• High chemical stability
• Very good resistance to aging
• Excellent resistance in oils and greases
• For use in the food, beverage and pharmaceutical industries
Leak-proofness
Our gear units are equipped with high-quality radial shaft seal rings and checked for leaks. However, a leak
cannot be fully ruled out over the length of use of a gear unit. If you use a gear unit with goods incompatible
with the lubricant, you must take measures to prevent direct contact with the gear unit lubricant in case of a
leak.

2.6.5 Reverse operation
To ensure lubrication for circulating gearing parts during cyclic reverse operation from ± 20° to ± 90° at the
output, pay careful attention to the position of the output shaft for the horizontal mounting of the gear
unit, as shown in the diagrams below. The images show the center position of reverse operation. Cyclic reverse operation ≤ ± 20° on request.

Notes
• If you use the solid shaft without a feather key (G), you must note the position of the mark during assembly.
• As an alternative, you can use the solid shaft with a feather key (P). In that case, the feather key functions for position orientation. For a backlash-free connection, also use a clamp.

3.3 Dimensional drawings
In this chapter, you can find the dimensions of the gear units as well as example dimensions of the mountable motor adapters.
Dimensions can exceed the specifications of ISO 2768-mK due to casting tolerances or accumulation of individual tolerances.
We reserve the right to make dimensional changes due to ongoing technical development.
You can download 3D models of our standard drives at https://configurator.stoeber.de/en-US/.

In the table above, you will find example motor connection dimensions for the MB motor adapter. Note
that when dimension c is lengthened (depending on the motor used), dimensions c6, l5 and lg are also
lengthened accordingly.
You will find additional motor connection dimensions for the MB motor adapter in our STOBER Configurator
at https://configurator.stoeber.de/en-US/. Here, you can directly download a 3D model of your drive.

3.5.2 ServoStop motor adapter with brake (MB)
In this chapter, you will find the description and technical data of the motor adapter with brake.
3.5.2.1 Properties
• Electrically actuated spring-loaded brake for dry running
• Featuring backlash-free plug-in coupling (jaw coupling) for easy removal of the motor with the axis
braked in any position
• Electrical release monitoring in the terminal box of the motor adapter
• Manual monitoring of wear via air gap checks with a feeler gauge
• As a single brake or together with the motor brake as a redundant brake system
• Manual release (optional)
• Radial shaft seal rings made of FKM with two sealing lips
• Four oil drain holes to protect the brake from oiling up in case of leakage
• Fast and easy motor attachment

3.5.2.2 Brake
A quiescent current brake is integrated into the motor adapter. It has the function of a holding brake. Braking from full speed, e.g. in case of a voltage drop or an emergency off in hazard situations, is still possible.
The brake can be used as a single brake or together with the motor brake as a redundant brake system.
Function
The brakes installed in the motor adapter are electrically actuated spring-loaded brakes for dry running. In
the de-energized state, braking takes place using spring force. The brake is released by an electromagnetic
DC coil before the motor is switched on. The switch-on time t2B (release time) is the time until the anchor
plate releases from the axially moving brake disc and is magnetically held to the coil body. In this state, the
brake is released and the coupling hub can rotate. In order to switch off (motor and brake), the residual
magnetic flux of the iron parts (anchor and coil body) must be reduced; the associated time t11B until the
start of torque generation is defined as a response delay when linking. The link time t1B is the time until the
braking torque has built up to the nominal braking torque.
Manual release
Optionally, the brake can be equipped with a manual release.
Pressing the manual release deactivates the electronic actuation of the brake. Before pressing the manual
release, you must establish the safety of the machine (e.g. protection against falling).
3.5.2.3 Electrical connection
• Terminal box (standard)
• Plug connector (optional, not possible in combination with release monitoring)

3.5.2.4 Monitoring
For monitoring the brake system, there are generally two options:
• Manual monitoring of wear via air gap checks with a feeler gauge
• Electrical release monitoring in the terminal box with a non-contact and wear-free proximity switch
